Now, in Krugman's defense, he did not demand that the Fed create a new housing bubble; he just suggested it as a good idea to jumpstart more consumption. He wrote back in 2002:
To fight this recession the Fed needs more than a snapback; it needs soaring household spending to offset moribund business investment. And to do that, as Paul McCulley of Pimco put it, Alan Greenspan needs to create a housing bubble to replace the Nasdaq bubble.
This, my friends, is better known in my home state of Tennessee as the "hair of the dog," which is what some of the Good Ole Boys take after a night of guzzling down lots of "Lynchburg Lemonade." Since the stock market was in the toilet, what better way of trying to "stimulate" consumption without the economy producing anything than to do it in the housing market!
The problem here is not withKrugman's recommendations, as awful and stupid as they were (and still are). The problem is more basic; Krugman's Keynesian "economics" is stupid, wrong-headed, and as crude a "theory" as the economics profession could create.
To his "credit," Krugman actually admits that he wrote that Really Stupid Comment. Furthermore, he does not exactly disown it:
Guys, read it again. It wasn't a piece of policy advocacy, it was just economic analysis. What I said was that the only way the Fed could get traction would be if it could inflate a housing bubble. And that's just what happened.
Uh, sorry. It was advocacy. Bubbles exist because of easy credit and easy money, and Krugman already is on the record as claiming that inflation will give an economy "traction," which is Keynesian-speak for "stimulating" spending.
